Need some simple help

Ok. So here what i need, we current set the mode of our game via a var with php.

The score system is in its own thingy not sure what it called.

So in the root main scene i put:

if (modeid=="0"){mode = 0  }
if (modeid=="1"){mode = 1  }
if (modeid=="2"){mode = 2  }

Then in the highscore area i put:

function New() {
      if (_root.mode = 0) {
    getURL("http://domain.com/scorepost.php?score="+_root.Score + "&level="+_root.level +, "_top", "POST");
       }
      if (_root.mode = 1) {
    getURL("http://domain.com/scorepost1.php?score="+_root.Score + "&level="+_root.level +, "_top", "POST");
       }
      if (_root.mode = 2) {
    getURL("http://domain.com/scorepost2.php?score="+_root.Score + "&level="+_root.level +, "_top", "POST");
       }
       Show();
       gotoAndStop("Display");

   }

However for some reason no matter what is always uses mode 2? Anyone see the problem?
